F. H. MRLLEH DXSCONNECTING SWITCH Filed sept. 24. 1.920

NVENTOR WHTN ESSES:

j Mmmm of spaced terminal combination with spaced terminal members one of which constitutes a pivotal support, oi an actuating arm pivotally supported entirely by one ot' said members and including a blade member pivoted at the outer end or' the arm and adapted to engage one of the terminal members, and means for positively actuatingl and varying` the relative. angular positions ot the arm and the blade meniber, as the arm is actuated.

3. ln a circuit-interrupting device, the combination with spaced terminal members, ot' a bridging switch arm structure pivoted adjacent to one end to one member thereot and wholly supported thereby comprising intermediately pivoted positively relativelymovable portions constructed to swing in an are ot' less radius than the dist-ance between the terminal members.

4r. Switch mechanism comprising a pair of spaced terminal members, an articulated folding blade member pivotally connected to one terminal member to turn bodily relative thereto and adapted to engage the other terminal member and an actuating member pivotally connected to one section of the blade member for positively moving the blade sections angularly with respect to one another. 5. Switch mechanism comprising a pair members, an articulated P,folding blade member pivotally mounted to move bodily relative to one of said members and having two pivotally connected sections and operating means for positively moving the sections angularly with respect to one another as the lblade member is moved to open or closed positions.

6. Switch mechanism comprising a pair of spaced terminal members, an articulated folding blade member having one section pivoted to one terminal member and another section having a contact portion adapted to engage the other terminal member, and said arm being constructed to tuin as a whole about. its pivot, means pivoted to the second section for positively relatively moving the sections. ,f v

7. Switch mechanism comprising a pair ot spaced terminal members, and a folding blade member for connectingr the terminal members comprising three bars,` two of which are pivoted eccentrically to a support and pivotally connected eccentrically to the third bar which engages the other terminal l member.

8. Switch mechanism comprising a pair of spaced terminal members, and a folding blade member for connecting the terminal members comprising ltwo conducting bars pivoted to one another, one of which is pivoted to one terminal and the other of which is adapted to engage the other terminal and a third operating barso pivoted to the first said terminal and to the second said bar that relative angular movement of the lirst and second bars is positively imparted thereto when the operating bar is moved.

9. Switch mechanism comprising a contact member, a switch blade member and an operating means therei'or, so pivota'lly connected to the blade member that it positively moves the blade member in a curved path, the blade member being disposed substantially parallel in each position to every other position thereof'.

10. A switch comprising two stationary terminal members and an articulated switch arm supported adjacent to one end only and having link sections so pivotally connected as to cause angular movement therebetween upon movement of said arm about one of said terminals as an axis, said arm having a contact portion that coacts with the other terminal but which in its open position is adjacent to said one terminal member.,l ll. A. switch comprising two stationary terminal members and an articulated switch arm supported adjacent to one end only and having link sections so pivotally connected as to cause angular movement therebetween upon movement ot' said arm about one of said terminals' as an axis, said arm having a contact portion that coacts with the o .ther

terminal.

l2. ln a switch, the combination with two spaced-stationary terminal Structures and a contact portion connected to each thereof, of means t'or moving said contact portions relatively to each other from a position in which the contact portions engage each other whereby the contact portions are disposed adjacent to the respective terminals thereof and separated a distance substantially equal to the shortest arcing distance between said terminal structures, said means comprising a switch arm pivotally mounted adjacent to ,one end on one of said terminal structures and adapted to swing bodily about its pivot.

13. A switch comprising two stationary terminal structures, a contact portion connected to one of said structures, a folding switch-arm structure including al link mounted on the other terminal structure for pivotal movement laterally to one side only ot a line between the terminal structures and a link pivotally connected to the outer end of said lirst link and carrying a contact portionor cooperation with said first contact portion and means for positively cliccting relative angulaixnovement of said links upon movement of the first-named link about said other terminal.

14. A switch comprising two terminal members and an arm structure arranged for pivotal movement about one of said termi-LV nals and comprising a plurality of relatively movable members pivotally connected to toi-n1 a polygon, one of said members having mossos a contact member 'for enacting with Hw other terminal.

15. A switch cmanprisng` two tcrminal members and up armstructmo arranged im 5 pivotal movement about ono of said. termi.-

nals and comprising a plurality of relatively movable members pivomiiy counccizcd to form a polygon, one of said members? having @cont-act member foi' zo-acting with the oher terminalssaid pivotslly-cormectcd members W boing su tantally parallclim the 'open and closed positions o the switch.
